摘　　要：随着P2P网络规模和用户量的增加,P2P环境下的信息量也随之飞速增长,给用户在搜索、定位和获取信息资源上都带来了巨大的困难。以全分布式非结构化拓扑结构为基础,采用Gnutella协议,提出了一种全新的P2P网络优化模型——NIP2P。NIP2P是将兴趣分组和物理位置相结合的P2P模型,可以提高搜索效率,缩短搜索路径,减轻节点负担,降低网络开销。the information amount rises rapidly with the intense increment of both users＇ quantity and network＇s scale and caused a serious problem,difficulty in searching,locating and retrieving resource.We presented a new P2P network model named NIP2P which based on the Gnutella protocol and decentralized unstructured topology in this paper.NIP2P is a P2P model which combining the interest grouping and physical Location.It is not only enhance searching speed rate and successful rate,but also decrease node load and network cost.
